“Members of the Kindness Rocks Project, spearheaded by KindRocks Florida, organized a complete remodel of the memorial in Pompano Beach dedicated to fallen Broward Sheriff’s Office Sgt. Chris Reyka,” the organization wrote in a statement. “Kindness rocks were collected and created by local residents specifically for the memorial. In addition, new plants and garden materials were also donated.”

Kindness Rocks describes a viral trended popularized in 2015 in which people, especially children, paint pebbles, rocks and stones to place at memorial sites for friends, family and loved ones who have died.

One of Reyka’s sons, Sean, also a former Marine, continued to follow in his father’s footsteps and joined the Broward Sheriff’s Office as a sworn deputy. Reyka also left behind a wife, Kim, and children Ashley, Autumn and Spencer.

Reyka’s killing had remained unsolved for years after his death until 2013, when BSO announced that it was confident it had identified Reyka’s killer, Shawn LaBeet, who himself had died the same year in a shootout with Pembroke Pines Police after shooting and killing a Miami-Dade Police Officer and injuring three others.
